Northern Ireland's Health Minister Jim Wells has resigned after saying children brought up in a same-sex relationship were more likely to suffer abuse.

The comments were made at a hustings event in County Down last week. He later apologised for those comments.

In a statement, Mr Wells said he was stepping down to care for his sick wife.

Unite union general secretary Len McCluskey has said he expects Mr Miliband to work with "any progressive party" if he becomes prime minister.

During a campaign visit to Scotland, Mr McCluskey told the Guardian: "I'm expecting Ed Miliband to be prime minister and, in those circumstances, I would expect him to work well with any progressive party who seeks to support the vision that he has of changing Britain for the better."

He also said it would be "wrong" for Mr Miliband to attack the SNP - "who have a manifesto that is anti-austerity,which is Unite's policy" - as his union's membership in Scotland was "pretty well split" between support for the nationalists and Labour.

The New Statesman has come up with an interesting list, external of the 10 seats to watch on election night. Among them are the well known - Thanet South, where Nigel Farage hopes to win, and Sheffield Hallam, where Nick Clegg's future will be decided - but also some less familiar battlegrounds. They include Southampton Itchen - "the only Labour-held seat that the Tories might win" - and Berwickshire, which "may be the most interesting seat in the UK".

Nigel Dodds, the Democratic Unionist Party's leader at Westminster, has expressed alarm at elements of the Conservative Party's campaign over the potential consequences of the SNP propping up a Labour government.

In an article in the Guardian, external, Mr Dodds condemns any attempt to question the legitimacy of a government supported by the SNP.

"This is where the campaign south of the border has so alarmed me," he writes. "Glib and lazy talk about SNP MPs somehow not being as entitled to vote in every division in the Commons, as any other British MP, simply fuels nationalist paranoia."

Mr Dodds also takes a swipe at Conservative plans to allow only England MPs to vote on England matters, as a constitutional mess.

We're in a new age of multi-party politics, Natalie Bennett tells BBC Breakfast, as she argues in favour of changing Britain's electoral system. The party wants a proportional representation voting system, rather than the current first-past-the-post. We also want an elected House of Lords, she says - but adds that they would consult the public, via a people's constitutional convention.

Green leader Natalie Bennett seems to be struggling with a croaky voice this morning. The general election campaign is taking its toll, perhaps? She stresses the need for more affordable housing, and also argues for a rebalancing of the economy.

Now Hilary Benn has hopped over to Today. "Communities are going to have to take responsibility" for housing those who need homes, he says.

But wouldn't restricting homes to those who've lived in an area for several years hinder the mobility of the young labour force?Mr Benn says they're only talking about half the homes in any development so the rest would be available to anyone. It would be up to the local authority to decide how to use those powers, he adds.

On Labour's idea to block above-inflation rent rises, Hilary Benn insists this isn't like the 1970s. He says the system the party is proposing - which also includes three-year tenanices - already works in a number of other European countries. "It's about providing a fair balance" between the needs of tenants and landlords, Mr Benn adds.

Shadow secretary of state for communities and local covernment Hilary Benn explains Labour's housing policy

All first-time buyers wont have to pay stamp duty up to £300,000. But "local poeple" - those who've lived in an area for three years - will also get the "first call" on any new homes being built. He says local authorities will have the power to put that planning condition on 50% of any new homes.

Doesn't that just exclude people who might have moved to an area for a dream job, say, he's asked?

"This is in part about consent," Mr Benn says, arguing that if a community knows that local people will have first dibs on some of the new homes "it will help unlock consent" for development.

None of the manifestos are specific enough to be properly judged, the founding chairman of the Office of Budgetary Responsibility, Sir Alan Budd, tells Today. "There isn't nearly enough detail" of the type the OBR looks at, he says. Giving the example of cracking down on tax evasion - as all parties have promised to do - Sir Alan says "we're really in the dark" about how they'd do it. Similarly on the subject of cuts, the Conservatives, in particular, have not provided the information the public want and need to make proper judgements.
